Types Of Software Testing - Why Is Testing Important?

Usually, we don't think about how a lot effort developers ought to put into providing users with a high-high quality product. Programmers will not be the only people who take part within the software development. For correct functioning, the program should be tested. And this job falls on the shoulders of QA engineers. What methods do they use for good, proper, basic testing? Let's consider this subject!

Widespread software testing types

In the event you order a new website or mobile app from a software development company, for instance, testing providers are included within the development process by default. However how does it occur? As a rule, the primary QA engineers carry out a Requirement analysis. It allows testers to grasp what the app ought to do and learn how to avoid bugs.

Then QA engineers begin making use of varied types of testing to specific software. These types embody the following:

Acceptance testing. Testers confirm whether or not software meets all acceptance criteria. Then it is as much as the client to make a decision whether or not the software will likely be despatched for revision or can be accepted.

Smoke testing. It is much like acceptance testing. At this stage, QA engineers make a short cycle of tests to check how the new product performs its functions, how it works, and how it is launched.

Regression testing. It is applicable if throughout the development process some changes in source code are made. But when we'd like particular functionality to work properly, the operation might not work after certain changes. So regression testing allows specialists to seek out out whether required functionality works properly and as well as it used to.

Sanity testing. It is a focused testing oriented for affirmation that one operate or another is working according to requirements stated in the specification. It's a subset of regression testing.

UI testing. The tester verifies whether the software meets requirements of graphic user interface, and whether it's made in a single style. It implies testing with different screen resolutions, compatibility with varied Internet browsers, as well as the testing of localized variations - translation accuracy and the name length of interface elements.

Permission testing. That's where QA engineers ought to check how the permission system is functioning within the software that's being tested. For example, you might be an abnormal consumer, and it will have been very strange in the event you had access to the administrator's access rights, would not it? And testers need to be sure that everything is working properly.

Usability testing. QA engineers must understand how you can make the final product user-friendly. So that they put themselves within the sneakers of frequent customers - they should test the software's usability, and discover out if it is straightforward-to-use or not.

Advanced testing types - why are they mandatory?

In most cases, all testing types considered above will help specialists to make good testing. But if your product is non-customary, the necessity in advanced testing could arise. Advanced testing includes the following:

Sprint zero activity. It signifies that QA specialists start testing even before the software is finished. It makes it attainable to avoid bugs at an early stage.

Automated Functional and Regression testing. Automation makes it attainable to get fast results and to fix all bugs as quickly as possible. Additionally, this testing type lets you launch the test with varied parameters: a couple of variations of input and anticipated data.

Compatibility testing. It is very important understand how the product is suitable with system components and other apps.

Interrupt testing. Everything is easy here - an understanding of how the product will work after an surprising interruption.

Load testing. What will happen to your app if too many customers start using it concurrently? That's what testers must find out after which create the maximal load for the software.
